VIBRATING MOTOR.

Leraars.

To @ZZ who/mit may concern: Be it known that l, KARL'EDISON, a citizen of the United States, and a resident of Spring Valley, in the county ofV Rockland and State of New York, have invented a new and Improved Vibrating Motor, oi which the following is a ifull, clear, and exact description. n

llt has been common practice to provide in connection with figure toys a` motor which will be capable of causing a vibration within the body of the figure so that the iigure may be caused to rock upon its supporting elements, which may be made to representV huma-n feet so as to cause a motion on the part of the figure to produce the illusion of walking.

These prior vibrating motors have usually consisted of a pendulum having a short swing, and in numerous instances associating stops for such pendulum against which the arm ofk the same swings with moreoix less violence, so as to provide a sharp yvibration.

Obviously this action will' tend to wear the parts of the motor,- and at best the lite of one of these motors is extremely short. Further, the vibrating motion and conse-y quent movement on the part of the gure has left much to be desired.

Further, the uses of this type of motor have been limited purely to the purnoseof imparting vibration, and it has proven inments upon a conventional motor base.

The ratchet mechanism iny all types of spring motors has also lett 'ni-uch to'be desired'in that particularly small commercial, or, in other words, cheap motors have been provided with ratchets which aitera certain amount of use and consequential wear,

have, failed to hold the spring, resultingin the same back-lashing upon the winding key being released andthe spring accordingly being snapped, rendering the entire motor useless.

llVith the above defects inmind I have constructed a new type of vibrating motor which will set up a vibrating motion of a far more useful purpose, in that when the motor is associated with toys adapted to move in such a manner as to give the illusion orf walking a far more improved Inotion will be imparted to the same.

This motor may also readily be adapted Specification of Letters Patent.

eiiieiently while'extending ink either an upg right or downward position in contradistinction to the conventional pendulum motors employed for vibrating purposes which will operate merely in a downward extending position. A. still further object ofthe invention is the construction of a pawl inechanismwhich may be relied upon implicitly in?y that no danger off non-operation on the part of the pawl exists, so that a breakage of the sprin due to baclclashing, is entirely precluded.

Reference is had to the attached sheet of drawings which illustrates a practical embodiment of my invention, and in which:

Figure l is a front view of a motorconstructed in accordance with myinvention;

Fig. 2 is a side view of the same; Fig. 3 is a sectional view through the motor taken along the lines 3&3 of Fig. 2; s Fig. 4 is 'an enlarged sectional view taken v along the lines 4-4 of Fig. l, and showing in detail certain portions of the rpawl and ratchet mechanism, and,

als` designate similar parts, and the reifer` ence numeral l indicates a base with which` the motor may be conveniently associated,

the motor including front and rear plates f2, a driving element, such as a spring 3, ay key for winding the same 4, and a conven, tional train of gears 5 terminating in the usual escapement 6 from which extends outwardly a shaft 7. n

ssociated with the outer end of the shaft 7 in any suitable manner, such as by means of an encircling portion clamped in position lthrough the means oit a set screw 8 is a lever including a downwardly extending part 9, y

' from the lower endrof which there is a ,porel tion extending outwardly and upwardlyV in a bowed form, as at'lO,'and encircling half y of the shaft 7, the upper end of such lever terminating in a weight ll, conveniently associated with the same, as for instance, by means oit' a screw l2. n

lt will now be appreciated that upon oiperation of the escapement and a 'consequential rocking of the shaft 7, the downwardly extending portion 9 and bent portion 10 of` the lever` will be rocked, resulting` in an oscillation of the weight 11.

It will now be noted that by means ofthe downwardly extended portion 9 that the part 1() may be made of a proportionately great length, and due to the over-,balancing effect of the weight 11', which over-balancing is facilitated by the rocking of the shaft 7 in" the direction Vin which the weight 11 tends `to oscillate, a greatly improved vibrating eect will be produced, which vibrating effect will also be procured upon the motor, contrary to the position illustrated in the drawings, being extended in a downward plane.

Thus it will be understood that the weight and lever might be set to normally occupy dead center7 position and from which posi-` tion they will be caused to move by means of the shaft 7, this` action being produced due to the overbalancing eect of the driving mechanism associated with the shaft7 Y subsequent to returning the parts to theirY normal position or plane.

Referring now more particularly toFfigs. 4 and 5, it will be seen that the spring 3 has rotatably associated with its shaft 13 a gear 14 formed of radially extending open-v ings 15, through its body portion, rotation on the part yof such gear with respect to the shaft 134 being afforded by means of a mounting hub 16. A ratchet conveniently 'including a plate of spring steel 17 is fixedly secured to the hub 16, its outer edges terminating at a point adjacent the lower edges of the radial openings 15, such," plate being, however, provided with tongues 18 adapted to serveas pawls by virtue of their engagement with openings 15 serving as a ratchet,

' it being noted that the tongues 18 extend beyondthe plates 17, and approximately parallel to the outer edges of the same.

It will now be appreciatedthat upon a winding effort being` exerted upon the key 4 that the spring 3 will have tension im,- parted to it, the hub 16 rotating with the shaft 13 upon a motion of the key 4 and consequential tension of the spring 3. This rotation will be imparted to the hub 16, and will cause a movement on the part of the plates 17 and associated tongues 18 with respect to the gear 14, the rear ends of 'the tongues 18 engaging the radial openings 15 of such4 gear and providing a pawl and ratchet operatingmechanism which may be relied upon implicity, and which, at` the same time, will be extremely economical to manufacture.

Now with respect to utilizin the' motor for other than causing the illusion of walking of a figure, it will be seenthat an operating rodV might readily be applied to the screw 19, 0r to the point12 of engagement of the weight with respect to the upper end of the lever. `lt will now be appreciated that a rod attached to either point, but preferablythe. latter, will be reciprocated and impart vreciprocating motion to any mechanism with which it might be associated.`

Obviously numerous modifications of structure might well be resorted to within therscope of my invention, which I claim as: 1. A motor including a shaft, a driving medium connected `with such shaftpa hub immova'bly secured thereto, Va gear wheel rotatably mounted upon such hub, a pawl including a plate portion andtongues extending from such plate portion and parallel to the outer edge thereof,`the rear ends of 'such tongues being adapted to engage radially extended openingsformed through nthe body of such gear.

2. A vibrating motor, including a lever, a shaft, the lowerend of said, lever being secured to said shaft, a weight attached, to y the upper end of said lever, said weight normally occupying a plane at which the lever and weight will be in dead center, and y i means for oscillating saidshaft to rock said lever and weight to` a pointto one side of` the opposite4 end of saidlevcr being bowed o and being formed with an upwardly extend-, 4

ing portion beyond said bowed part,.a shaft,

the upwardly extending end portion ofsaid lever being secured to said shaft, whereby to rock said lever and weight, to rock/che` ent-ire motor.

5. vibrating, motor,jincluding a lever a weightattached to the upper end ofsaid lever, a shaft, means for oscillating,said` shaft, the lower end `of said lever being attached to said shaft, whereby when said shaft is oscillated the lever and its associated weight will be rocked, causing a rocking of the entire motor.
